The wax palms get their name from a natural wax that covers their trunks which was also used for candles until the Colombian government passed a law that now protects the vulnerable trees. In addition to their waxy coating, the palm trees have also in the past been hunted for the Catholic holiday, Palm Sunday, as well as for architectural purposes.
The trees are now protected though, and it is not uncommon for Cocora Valley to be covered in fog, which gives the valley somewhat of a “Jack and the bean stalk” sort of feel to it. Standing below the palm trees and losing their green caps in a heavy fog can be almost as impressive as the sight of the palm trees on a clear day. However, there is nothing more humbling than standing directly beneath the palm tree that makes the mountains look small.
